The Ultimate Pi Day Fun Facts

Only 39 digits past the decimal are needed to accurately calculate the spherical volume of our entire universe.

Albert Einstein was born on 3/14.

Pi is the most recognized mathematical constant.

The fraction 22/7 is a well-used number for Pi.

A more accurate fraction of Pi is 104348/33215.

During the famed O.J. Simpson trial, there were arguments between defense attorney Robert Blasier and an FBI agent about the actual value of Pi, seemingly to reveal flaws in the FBI agent’s intellectual acumen.

Ancient mathematicians tried to compute Pi by inscribing polygons with more and more sides that would more closely approach the area of a circle. Archimedes used a 96-sided polygon. Chinese mathematicians Liu Hui inscribed a 192-sided polygon and then a 3,072-sided polygon to calculate pi to 3.14159. Tsu Ch’ung and his son inscribed polygons with as many as 24,576 sides to calculate Pi (the result had only an 8-millionth of 1% difference from the now accepted value of Pi).

If you were to print 1 billion decimal values of Pi in ordinary font it would stretch from New York City to Kansas.

The record for the most digits of Pi memorized belongs to Chao Lu, of China, who recited pi from memory to 67,890 places in 2005, according to The Guinness World Records.

3.14 backwards looks like PIE.

“I prefer pi” is a palindrome.

One of the earliest known records of Pi was written by an Egyptian scribe named Ahmes (c. 1650 B.C.) on what is now known as the Rhind Papyrus. He was off by less than 1% of the modern approximation of Pi (3.141592).

In the Greek alphabet, Pi (piwas) is the 16th letter. In the English alphabet, P is also the 16th letter.

William Jones (1675-1749) introduced the symbol “π” in the 1706, and it was later popularized by Leonhard Euler (1707-1783) in 1737.

Literary nerds invented a dialect known as Pilish, in which the numbers of letters in successive words match the digits of Pi. For example, Mike Keith wrote the book “Not a Wake” (Vinculum Press , 2010) entirely in Pilish:Now I fall, a tired suburbian in liquid under the trees,
Drifting alongside forests simmering red in the twilight over Europe.

(“Now” has three letters, “I” has one letter, “fall” has four letters, and so on.)
